Solid Opening... No Middle Game???

can someone help me figure out how to plan during the middlegame??? i feel like my opening is solid but i dont know what to do afterwards...

I'm guessing you're white, right?

OK, imo move 10. Instead of moving your queen to a position where it threatens nothing, and as you found out, just allowed black to push it around and develop, why not castle first? Until then you had not anything particulary wrong.

The middle game is where you start to think how am I going to attack the king. In other words, what are my opponents weakest squares? The bishop on the c file can't do much by move 9/10 as its staring straight at a protected pawn. If black attacked it with the knight or pawn, then the d square would be much better. You could then look to attack the king that way putting the queen on the b1 square for example, and perhaps move a knight round to look at attacking the h7 pawn, which makes a nice target. You just need to think of a plan of removing the knight, such as pushing the e pawn, trade a knight or sac a pawn for example.

Blacks Bc6 was an odd choice, and many more from there but not surprising given their rating.

You would learn far more playing players in 1400-1600 range, even weak players can get a decent position for 6 or 7 moves, its knowing what to do after that is the hard part.

like ^^ said, try to attack the opponents king in that type of middle game and move 10 was pretty useless. maybe you can try to develop your pieces near your opponent's king in the middlegame, provided that you aren't going to lose if you do.

I wasn't sure if this statement was specifically about the game in question, or if it was more general.  Although I feel somewhat uncomfortable trying to correct someone higher rated than me, if it was a general statement I must disagree.  Once you decide to start planning, an attack on the king is only one possible option, if the position does not lend itself to a kingside attack then a different strategy is required.

I mean attacking the King in a general way, that could encompass anything from what pieces are in your way to the opponents king, which file can be opened easiest and be most inconvenient to defend for your opponent, and targeting loose pieces.

This is simplified, it also depends on stuff like what opening are you using. If I'm white and play 1.c4 I'm looking to attack the center and then flank the king, if I'm black I play 1.g6 and never look at attacking the king until many moves in to the game, for me that time in the early mid game is spent making a fortress and waiting for white to commit themselves, before I counter.

Only meant to differentiate from the beginning in that (for newer players at least) the first 8 moves is usually to always develop your position. There may be occasion where you decide to go on the attack immediately, perhaps in a blitz game, but mainly those first few moves are to consilidate your position on the board, get your king safe behind a pawn line and move your knights and bishops in to play, after that is where you look at potential plans to attack and go for the ultimate target.
